0 the curved path through which objects in space move around a planet or star -- （天体围绕行星或恒星运行的）轨道
Once in space, the spacecraft will go into orbit around Earth. 一旦进入太空，航天器将进入环绕地球的轨道。

Qualitatively similar orbits are obtained in the many par ticle calculations.
In opposition to this, chaos is effective for causing rapid desynchronization, because of its characteristic exponential divergence of nearby orbits.
Dynamically we find most orbits to be stable over long time scales and typically this happens in a wider parameter area than in co-rotating systems.
The bar will hence be able to relocate stars, and stars with low or high metallicity could be found far away from their original orbits.
We only need that the return maps at periodic orbits are diagonal on the stable and unstable manifolds.
In most cases, those planets follow orbits with significant eccentricity, leading to substantial seasonal temperature excursions.
In most cases, those planets follow orbits with significant eccentricity, leading to substantial temperature excursions.
Indeed, nebular drag and collisions would ensure that orbits with zero eccentricity were preferred.
